Every product for 8 lights is about 400 or less.

Is it possible to diy for cheaper and better?

Most of these items have analog timers.

And dont think you can fire 2 lights at a time then so on till all 8 fire up.

Start with a SIEMENS EQL4100 load center, then get 120V or 240V breakers, depending if your ballasts are 120V or 240V. A 2-pole 60A contactor (120V coil) with a timer will supply power the loadcenter. All parts shouldn't be more than $300, but you will have a safe 8 light controller, better than anything OTS, cheerz. If you want to power on 2 lights at a time, then get 4 x 30A/2-Pole contactors and a PLC, PLC is about $200.

If it is the small rectangle one i have it.

240v so a 60 amp 2 pole breaker got it.

What do you recommend for the contactor?

Just need the contactor what do you .

I'm sure it will be a bit more expensive than a 2pole... however can still be used... just hook up 2 poles and leave 3rd empty

Just pulled the trigger on a siemens logo 8 plc starter kit.

I have to buy a ranco hight temp shut off relay. Now.

Looks like the 3 pole 60amp contactor is cheaper then the 2 pole.

Do u need ssr to fire up the digi ballast or can it be wired from contactor to receptacles?

[hvac guy]

Contactor works fine, an SSR is also an option, more expensive. The Siemens logo is fairly straight forward, when you have analog inputs/triggers, then it gets a bit more complicated, if you need help with the logo software, let me know.

I built mine for 6-1000w/220v for well under $200
with sequential start for 2 at a time.
it meets all state and national electrical codes.
it's very portable if you build it by the plans
mine is more permanent version attached to the elec. panel

here pics of mine. I wanted to add more lamps down the road and with this
i can upgrade easily to 12 lamps
going this route i saved a pretty penny to spend on other equipment when i built my room.
